Rental refrigeration systems / Rental chillers
Do you need additional capacity on short notice, or are you planning a renovation that requires a flexible cooling solution? Then get in touch with us!
Container Refrigeration Systems
Demand for modular energy centers has risen rapidly in recent years. The reasons for this trend can certainly be found in the quick availability, flexibility, and space-saving design of these high-performance ONI systems. From cooling and chilled water to heating and compressed air supply—including pumps, tanks, and control units—the entire system is arranged in a compact, space-saving manner within modular units.
Refrigeration Equipment & Technology
A reliable and energy-efficient supply of cooling water for production is a top priority for any business. That is why more and more companies around the world are choosing our energy-optimized and highly reliable cooling system technology
Highly efficient ventilation systems and room air conditioning
Our ventilation systems and room air conditioning solutions feature state-of-the-art technology and meet the highest standards of efficiency and reliability.
Cleanroom Technology
The need for a cleanroom environment, where exposure to airborne solid or liquid particles is minimized, usually stems from product-specific or hygiene requirements. The range of industry-specific requirements is broad, and the associated system engineering is correspondingly complex.
Ice storage
Almost every industrial facility generates waste heat. Use our heat recovery systems to harness this energy for heating your offices, factory floors, and much more.
Battery storage in a container
A container-based battery storage system is a scalable storage solution that ensures flexible access to electrical energy during operations.
Compressed air systems
A reliable and efficient compressed air supply is a top priority for industrial companies. In this context, “reliable” also means generating and supplying compressed air in the quality and quantity required for production processes, machinery, and equipment.
Cooling water for industrial facilities
Cooling water in industrial systems: hydraulics, standards, operational and process safety, and energy efficiency in the recirculation cooling loop with ONI-PowerSave.
Cooling Water Treatment for Industrial Facilities
Cooling water treatment for reliable cooling systems: Stabilize water quality; reduce corrosion and scale buildup.
Temperature Control Technology with Rhytemper®
Optimal manufacturing process. The unit costs of die-cast and injection-molded parts are largely determined by mold temperature control! This is because mold temperature control has a direct impact on process stability, product quality, and cycle time.
EtaControl®: Energy Efficiency in Manufacturing
EtaControl® from ONI helps plastics processors quickly reduce energy costs.
